A sexually explicit song Brian Mcknight recorded for an online porn company has been pulled from video-sharing website YouTube.com due to “inappropriate content”. The R&B singer wrote the racy track for YouPorn.com to thank web bosses for helping to sell a tongue-in-cheek song he released in April, titled, If You’re Ready to Learn, which offered sympathy to women left unsatisfied in the bedroom by selfish lovers. McKnight’s latest adult work debuted online this week, accompanied by a promo featuring girls in bikinis, but the clip was deemed too explicit for YouTube and banned. YouPorn executives posted a different version of the video minus the scantily-clad women in a bid to get around the ban, but that promo was also removed from YouTube. YouPorn representative Corey Price tells TMZ.com, “I can’t believe with all of the crazy content that is posted to YouTube on a daily basis that this video of all things is being pulled repeatedly! Apparently you can show videos of bomb making and people killing kittens, but a bunch of hot girls dancing around in YouPorn.com bikinis is outlawed.” McKnight has assured upset fans that the vulgar tunes are not an indication of his new musical direction – it was all part of a prank.
